Charity and Penitence
Charity: Visit for a suitable time their brothers and sisters in need or in difficulty (the sick, the imprisoned, the elderly living alone, the handicapped, etc.), as if making a pilgrimage to Christ present in them (cf. Mt 25:34-36)

Fulfill the usual spiritual and sacramental conditions and saying the usual prayers to gain plenary indulgence.

Actions which express in a practical and generous way the penitential spirit which is, as it were, the heart of the Jubilee.
  1. abstaining for at least one whole day from unnecessary consumption (e.g., from smoking or alcohol, or other goods of one's choice), or,
  2. fasting, or,
  3. practicing abstinence (from meat or other food according to the norms of the bishops conference) and donating a proportionate sum of money to the poor (such as one would save by the abstinence), or,
  4. supporting by a significant contribution works of a religious or social nature (especially for the benefit of abandoned children, young people in trouble, the elderly in need, foreigners in various countries seeking better living conditions), or, 
  5. devoting a suitable portion of personal free time to activities benefiting the community, or,
  6. other similar forms of personal sacrifice.
General Conditions:
The following conditions must be fulfilled whenever we seek to gain a Plenary Indulgence (complete remission of the temporal punishment due to sin). These general conditions are in addition to the specific conditions of the indulgenced work (e.g. a pilgrimage).
  1. Be Baptized and not excommunicated
  2. A subject of the one granting the indulgence. (Since it is the Pope granting the Jubilee Indulgence all Catholics of any Rite meet this condition.)
  3. Be in the State of Grace, at least at the end of doing the indulgenced work.
  4. Have at least a General Intention to gain the indulgence. (This can be fulfilled by making a general intention at the beginning of the day to gain the indulgences for which one is eligible that day, or, by making a specific intention at the time of doing the indulgenced work.)
  5. Do the Prescribed Work. (This is the pilgrimage, charity, penitence, etc., and any conditions associated the specific indulgenced work.)
  6. Sacramental Confession, several days before or after the indulgenced work. In a Feb. 2000 document on Indulgences the Apostolic Penitentiary stated that the allowable time should be considered to be "about 20 days." One confession suffices for several plenary indulgences. 
  7. Communion, several days before or after (to "about 20 days"), but is most fittingly received on the day that the work is done. A unique Communion is necessary for each plenary indulgence.
  8. Prayers for the Intentions of the Pope (such as a Creed, or an Our Father and Hail Mary, though no particular prayer is prescribed). These prayers may be made several days before or after, but are most fittingly made on the day the work is done.
  9. Detachment from all sin, even venial sin. Incomplete detachment from sin would result in the receipt of only a partial indulgence for that work. It is this disposition to renounce all attachment to our sins which opens our heart to the receipt of the full remission of the temporal guilt of sin, which God  desires to grant us through the Church.
